Nate's Toolbox
A collection of useful tools that I maintain, and some links to my favorites.
Epochs, other date/time formats, and time zone conversion.
Prototype folder layouts from outlines—ASCII trees before creating real folders.
Generate, validate, and detect different UUID types and versions.
Repair, validate, and beautify messy or pasted JSON.
Color palettes, format conversion, and a small engine for managing collections over time.
Create and tune QR codes, manage payloads and presets, and export assets from one place.
